Venting film lets off steam

A new steam venting lidding film from KM Packaging Service is compatible with polypropylene trays for ovenable meals and snacks.

A new steam venting lidding film from KM Packaging Service is compatible with polypropylene trays for ovenable meals and snacks.

The new film can be supplied as peel seal or weld seal, with or without KM’s anti-fog treatments. A high oxygen barrier is also available, where venting holes in the film are coated to prevent air getting in or out, hermetically sealing the tray. On heating in a microwave oven, the coating softens to facilitate ventilation.

Alternatively, pepper pot holes can be created in the centre of the lid, allowing steam to escape but keeping the seal intact. The hole cluster can be placed in virtually any specific position on the lid, depending on the contents of the tray and the desired ventilation effect – and can even extend to several hole clusters on one lid.

In addition to lidding, KM can supply the film as roll-fed bags for vegetables, and printed to promote branding while saving on unnecessary additional packaging.
